The tea grading system is an important basis for judging the quality and style of finished tea, and is especially common in the international black tea trade.

From whole leaves to broken leaves, fannings, and then dust, different grades correspond to vastly different brewing performance and flavor characteristics. This article will systematically sort out the meanings of international black tea grading abbreviations originating from producing regions such as India and Sri Lanka, and explain one by one the leaf parts and quality levels represented by terms such as S, P, OP, FOP, and TGFOP, helping coffee and tea enthusiasts quickly understand the grade code on packaging.
